High Performance Flowserve Logix 3800 Intelligent Digital Valve Positioner for Industrial Control Valves

Product Overview

The Flowserve Logix™ 3800 Digital Positioner is a robust, SIL 3-capable device designed for precise valve control in the most demanding oil & gas, chemical, and power applications. Its modular, position-insensitive design delivers reliable performance from -55 °C to +85 °C (-67 °F to +185 °F) while offering advanced predictive diagnostics and industry-leading air capacity with minimal consumption.

Key Features

• Rugged SIL 3-capable modular construction with IP-66 protection and non-contact magneto-resistive feedback sensor.
• Five integrated pressure sensors for real-time diagnostics including supply pressure, friction, leaks, and backlash warnings.
• Double-poppet pneumatic relay for up to 80 % higher air capacity with ultra-low bleed.
• Explosion-proof, intrinsically safe, and non-incendive certifications for global hazardous areas.
• One-button QUICK-CAL calibration completes setup in under 60 seconds.
• Fully encapsulated electronics with firmware upgradeability via HART or FOUNDATION Fieldbus.
